Research StudyTerminology

Research studies often contain language that may be unfamiliar to nurses. Some of the basic terminology that's commonly found in research studies are:

  • Abstract: a brief summary or overview of the research study.
  • Case Study: a collection of detailed information about a person or specific group.
  • Causality: the relationship between the cause and effect of a situation or event.
  • Consent: an agreement given by a competent person to participate in a research study.
  • Control Group: randomly selected participants from the research group who won't receive the experimental treatment or variable. Those in the control group will be compared with those receiving the treatment or variable under investigation to establish the effectiveness or ineffectiveness of the variable/treatment.
  • Double-Blind Study: a research study conducted in which neither the investigators nor the participants know specific details of the study, such as whether a placebo or trial medication is being administered.
  • Experimental Research Group: randomly selected participants from the research group who will receive the experimental treatment, medication, or variable.
  • Hypothesis: an educated guess about the expected outcome of a study.
  • Mean: the average score between two variables or outcomes.
  • Single-Blind Study: a research study conducted in which the investigators know specific details of the study but the participants don't.
  • Variable: an intervention, action, or medication that's being studied to observe its effect on the research group. For example, a group of oncology patients may receive a new cancer medication to study its effectiveness on reducing tumor cell growth. In this scenario, the new medication is the intervention or variable.
